Tank mates for pearl danios
We checked pearl danios against all 149 other species in our database for water temperature, pH, size, fin nipping, predation and aggression.
Good tank mates for pearl danios include cherry shrimp, nerite snail, neon tetra, panda corydoras, bristlenose pleco and bronze corydoras. Avoid oscar, boesemani rainbowfish and chinese algae eater: oscar can eat pearl danios: they're small enough to fit in its mouth once it's grown.
Pearl danios: 20–25°C (68–77°F), pH 6.5–7.8, adult size 6 cm (2.4 in), minimum tank 20 gallons (76 L). Full pearl danio care guide.
